有没有一种方法来查询一个嵌入式Flash元素，以确定可以在其上通过JavaScript执行的有效方法？

Is there a way to query an embedded flash element to determine the available methods that can be executed on it via JavaScript?

编辑： 目前看来，在IE浏览器这么简单

It appears that in IE it's as simple as

for ( i in flashNode ) {
    alert(i);
}

在很多点击，它们会出现一些列举的最后成员。

After much clicking, they will be some of the very last members enumerated.

仍然无法在Firefox确定这虽然。

Still not able to determine this in Firefox though.

推荐答案

虽然可以通过枚举得到回调＆LT;对象＆gt;在IE DOM节点，它们混合在使用DOM节点的所有其他的属性和它们不能是不保持已知属性的列表，以它们免受比较，然后采取两组的差异progamatically区分。

While it is possible to get the callbacks by enumerating the <object> DOM node in IE, they are mixed in with all the other properties of the DOM node and they are unable to be progamatically distinguished without keeping a list of known properties to compare them against and then taking the difference of the two sets.

这个方法是有问题的，因为性能可以任意添加到任何DOM节点。更糟的是，它只能在IE浏览器。火狐（也可能是其他人）不返回回调作为一个属性＆LT;对象＆gt; DOM节点

This approach is questionable since properties can be arbitrarily added to any DOM node. Worse, it only works in IE. Firefox (and possibly others) does not return callbacks as a property of the <object> DOM node.
